Monoxor III 4.0 OPERATION To operate the Monoxor III, you smply . . . • Turn the analyzer ON • Wat for the unt to warm up • Take a gas sample 4.1 Taking a Gas Sample Important! If the CO channel is set up for Auto Zero (refer to Section 3.4.3), ensure that the analyzer will be sampling fresh air (containing no CO) when turned ON.
Monoxor III 4.2 Ending a Test WARNING! Burn Hazard. Do not touch the probe after removing it from a flue. Allow the probe to cool before han- dling (about 5 minutes). After takng a gas sample, remove the probe and take the analyzer to an area contanng fresh ar.
Monoxor III 4.5 CO Sensor Error Screen When the CO channel s set up for Auto Zero (refer to Secton 3.4.3), a CO sensor error wll occur f the detected Carbon Monoxde level s above 50 ppm during the warm-up period. Note, however, that f the CO channel s set up for manual calbraton, the analyzer does not auto-zero the CO sensor during warm-up, and thus does not generate a CO sensor error when the analyzer s turned ON n an...
Monoxor III 4.8 Operating Tips • When an analyzer s brought n from a cold vehcle, let t warm up slowly to mnmze condensaton. Temperatures below freezng wll not damage the analyzer; however, brngng a cold analyzer nto a warm, humd envronment may cause condensate to form nsde the case.
